The month-long fest of test rugby began with New Zealand appearing at Soldier Field in Chicago, an aptly named venue as the All Blacks are going to find themselves under constant fire between now and the Rugby World Cup knockout stages in October.
They have lost two matches in the three years since the last tournament, they are the longest-ranked No 1 side in the world, they have seen off all-comers in the Rugby Championship and Europe, yet have returned home with no assurances that they will become the first side to retain a World Cup. Quite the opposite. Even though they are the team to beat, and despite the acclaim and garlands, there is a growing sense that the posse is closing in on them.
Here is why. The Springboks have no inferiority hang-ups when it comes to playing New Zealand, and are the only side to topple them this year. Australia have been riven by internal discord, forced to change coaches at this late juncture, yet have the most tantalisingly potent backline in world rugby, eclipsing even the Kiwis. They will only get better under Michael Cheika.
Ireland have shaken off their chokers tag against the Southern Hemisphere with two notable wins, with the scheming, cerebral influence of coach Joe Schmidt clear to see, while Wales have also put an end to the hex. Scotland are stirring and even France are showing signs of no longer being the basket case of European rugby.
